Unless you want to start using MATLAB, you’ll have to live with using j to denote your complex numbers. If you want to parse complex numbers using ‘i’ instead of ‘j’, you have plenty of solutions available already. The way numbers are parsed either by the language parser (in source code) or by the built-in functions (int, float, complex) should not be localizable or configurable in any way that’s asking for huge disappointments down the road. For one thing, the letter ‘i’ or upper case ‘I’ look too much like digits. This was brought up on Python’s bug tracker over a decade ago, and Python’s creator, Guido van Rossum himself, closed the issue with this comment:
The letter i can be easily confused with l or 1 in source code.In computing, the letter i is often used for the indexing variable in loops.

To download the sample code used throughout this tutorial, click the link below: If you need a quick refresher or a gentle introduction to the theory of complex numbers, then you can watch Khan Academy’s video series. Translate mathematical formulas directly to Python code.Take advantage of the built-in cmath module.Use complex numbers in arithmetic expressions.Represent complex numbers in rectangular and polar coordinates.Define complex numbers with literals in Python.You’ll explore vector graphics and sound frequency analysis, but complex numbers can also help in drawing fractals, such as the Mandelbrot set. Python is a rare exception because it comes with complex numbers built in.ĭespite the name, complex numbers aren’t complicated! They’re convenient in tackling practical problems that you’ll get a taste of in this tutorial. Your typical options are learning some specialized tool like MATLAB or finding a third-party library. Most general-purpose programming languages have either no support or limited support for complex numbers.
